Assura LVS SYNTAX ERROR

Zdeno
Zdeno over 10 years ago

Hello guys!

I am fighting with Assura LVS syntax error. This error is known problem there but unfortunately I can not resolve it still.
Assura LVS comparison runs just fine till the end and when the result should be shown there is a Syntax error in CIW:

Starting the Assura LVS Run: IPC Id ipc:4: pid 26375.

STATUS: Schematic and Layout Mismatch

*WARNING* (reader): extra ')' ignored at line 1 of string "1 044 "mosvar50_dev")"

1 0(6467 "ntie_device")

^

SYNTAX ERROR found at line 1 column 5 of file *string*

I tried also run assura command from command line with .rsf file:

/home/zdenko/cadence/assura/tools/assura/bin/assura /home/zdenko/cadence/workspace-ams180/ASSURA_LVS/pixel/pixel.rsf -cdslib /home/zdenko/cadence/workspace-ams180/cds.lib -gui

And the result was again with Syntax error:

....

parFETcomb Resultant: (nil psp 0 rf 0 bentgate 0 gcon 1 par 1 m 1 wt 3.48e-06 l 1.8e-07 nf 2)
parFETcomb Resultant: (nil psp 0 rf 0 bentgate 0 gcon 1 par 1 m 1 wt 3.48e-06 l 1.8e-07 nf 2)
parFETcomb Resultant: (nil psp 0 rf 0 bentgate 0 gcon 1 par 1 m 1 wt 3.48e-06 l 1.8e-07 nf 2)
Compare errors, please see /home/zdenko/cadence/workspace-ams180/ASSURA_LVS/pixel/pixel.csm and /home/zdenko/cadence/workspace-ams180/ASSURA_LVS/pixel/pixel.cls files.

*Error* lineread/read: syntax error encountered in input

*WARNING* nvn exit with bad status
*WARNING* Status 65280
*WARNING* Assura execution terminated


*****  nvn fork terminated abnormally  *****

I suppose that error is from file "ASSURA_LVS/pixel/pixel.lvsdb/extr" but what is strange that the syntax error is from inside the file and not from biginning, so the system can read the file:

.....

1 0 (6464 "nwsx_device")
1 0 (6465 "sub_dev")
1 0 (6467 "ntie_device")
1 0 (6468 "ptie_device")

.....

My OS is CentOs7. I had chosen it because CentOs6 could not run at my new PC. At CentOs6 and old HW LVS was running without any troubles.
I am using new 2014/2015 release (the same problem with 2013/2014):

Hotfix_IC06.16.080
Hotfix_ASSURA04.14.111-616

I also tried to link cadence libstdc++.so library with system libstdc++.so with no success.
I had to edit "share/oa/bin/sysname" for IC and ASSURA to use new kernel

#             2.6.* | 3.0.*)
            2.6.* | 3.*)
                  compiler="_gcc44x"
                  sysname="linux_rhel50$compiler"; sysnames="$sysname linux_rhel40$compiler $sysnames";;

Please anyone knows from where this error occurred?

Thank you very much, Zdenko

    Thank you Andrew,

    I sent the request to Europractice - Ref No: E40836.

    Can I send the task directly to Cadence support? I have a reference key, but I can not see any link for sending request at http://support.cadence.com/

    Best regards, Zdenko
